When the compound changes from a liquid to a solid, the molecules lose their energy, they slow down and thus come together and closer.  

Solid is one of the states of matter where the molecules or atoms of a compound stay close together in contact with each other and are not able to perform any movement. The kinetic energy of these molecules is very less and such compounds have a structural integrity.

Energy is defined as the capacity to do work or supply heat to any body. In any compound, the energy is stores in its chemical bonds. The transition of molecules from a less ordered state to a more ordered state results in the release of energy from the compound.

Elevated low-density lipoprotein cholesterol is more likely to increase the risk of cardiovascular in men than in women

Men generally develop CVD at a younger age and have a higher risk of coronary heart disease (CHD) than women.

It appears that men's coping with stressful events may be less adaptive physiologically, behaviorally, and emotionally, contributing to their increased risk for CHD.

CVD is the leading cause of death worldwide, yet important differences exist between men and women

During a woman's fertile age, estrogens have been found to exert beneficial effects on the cardiovascular system (CVS), which often protects women from atherosclerosis during this time.

Fossil evidence, biogeographical evidence, and anatomical evidence were some of the many types of evidence that Darwin utilised to support his theory of evolution by natural selection.

We'll examine a variety of sources of information to examine the evidence for evolution, including both anatomy and embryology. An evolutionary heritage can be determined by similar anatomical traits between organisms, including those that are only observable during embryonic development.

Molecule biology We can tell how closely related two creatures are by comparing and contrasting the "same" gene in those animals (i.e., a pair of homologous genes).

Biogeography - We can retrace the evolutionary history of species by looking at their geographic distribution.

Fossils - However, it confirms the existence of now-extinct species and occasionally captures potential "in-between" species. The fossil record is not a complete record of evolutionary history, forms on the path if present day species.

Without sufficient Soil permeability, plants drown, suffocate, dehydrate, and starve. Healthy soil consists of sand, loam, and clay of varying sizes. The area between these bits are labeled macropores and micropores, depending on their size.

Soil permeability, the property of soil that allows water and air to pass through, is one of the most important properties to consider for fish farming. A pond built on impermeable soil loses little water to leach out. The more permeable the soil, the greater the penetration.

Soil permeability is important for proper plant growth and development and helps plants absorb minerals and sugars. Poor soil permeability also results in mud and stagnant water.

Together, the circulatory and respiratory systems assist eliminate waste carbon dioxide from the tissues and deliver oxygen to the tissue.

The respiratory system is the one that helps to inhale oxygen and exhale carbon dioxide. And the circulatory system is the system that helps to supply oxygen from the lungs to tissues and helps to remove carbon dioxide from the tissue via the lungs. Both these process helps to supply oxygen in this way and helps to remove carbon dioxide as a waste.

First, the oxygen inhaled will be transported to the lungs and this oxygen will be exchanged with the blood that brings the waste (CO₂) from the tissue via the heart. Then, the oxygen will be transported to the heart from where the oxygenated blood will be supplied to the tissues. And the waste from the tissue will be carried via deoxygenated blood.

Genetic engineering uses a process of insertion of genetic material, which does not occur in nature, by a gene gun or other direct gene introduction methods, or by a specially built bacterial truck.

With the aid of sexual and asexual reproduction that occurs naturally, conventional breeding mostly relies on selection.  In order to create the desired crops more quickly than through selective breeding, genetic engineering involves directly changing an organism's DNA.

Any form of selection that results from an organism's capacity for environmental adaptation is known as natural selection. Contrarily, artificial selection is selective breeding that is imposed by a third party, typically humans, in an effort to increase the frequency of desirable traits.

Answer: Carbohydrates on the cell membrane help cells function properly. Carbohydrates do this in two ways: helping cells recognize each other and providing protection for cells.

Chemiosmosis is the passage of ions down their electrochemical gradient over a structure bound to a semipermeable membrane.

Protons, also known as hydrogen ions, will diffuse from an area with a high proton concentration to a site with a low proton concentration. Using an electrochemical gradient of protons across a membrane, ATP can be produced.

The oxidation of water, which is "divided" into protons and oxygen by the oxygen-evolving complex, replaces the electrons lost from Photosystem II (OEC, also known as WOC, or the water-oxidizing complex). Ten photons must be absorbed by Photosystems I and II, four electrons must pass through the two photosystems, and two NADPH must be produced in order to create one molecule of diatomic oxygen (later used for carbon dioxide fixation in the Calvin Cycle).

Explanation:

One reason why the water lily (Nymphaea spp.) lacks a waxy cuticle is because it is adapted to living in an aquatic environment. A waxy cuticle is a layer of cutin, a waterproof, protective coating found on the surface of plant leaves and stems. It helps to prevent water loss through evaporation and protect the plant from dehydration.

However, water lilies are adapted to living in an aquatic environment, where they are constantly surrounded by water. As a result, they do not need to worry about water loss through evaporation and do not have a waxy cuticle to prevent it. Instead, water lilies have evolved other mechanisms, such as thick, succulent leaves and stems, to help them absorb and store water.

The water lily lacks a waxy cuticle because it is generally present in the water, so it does not have the adaptation to save water, so it does not have the waxy cuticle, while these are the adaptations of the desert plants.

The water lily is significant as it has an important role in aquatic ecosystems because it provides food for a wide variety of aquatic animals, such as insects and fish, while its roots can help stabilize shorelines, prevent erosion, and purify water by removing excess nutrients. Its seeds are of great interest to humans due to their high demands.

Oceanic crust is generally younger than continental crust, being less than 200 million years old. It is made of basaltic rock, which is denser and more mafic than the granitic rock found in continental crust. Oceanic crust is thinner and more dense than continental crust, with average thickness of about 6 kilometers compared to about 35 kilometers for continental crust. Oceanic crust is also less buoyant and more prone to subduction.

Continental crust is generally thicker and less dense than oceanic crust, and is composed mainly of granitic rock. It is much older than oceanic crust, having formed over billions of years, and is also more buoyant due to its lower density. Continental crust is less prone to subduction and therefore is more likely to form mountains and landforms. It is also much thicker, with an average thickness of about 35 kilometers.
